There was another game from a year or two ago that found that more people bought Linux versions than Windows. I can't remember what that game was though.
How did emacs oss shit start? The guy made an OSS editor, and said I will customize it to your company's needs for my fees, and you just have to accept that my changes will all be oss. And if I do something cool for someone else you get those changes too.
Thats the point. You think Linus is having trouble finding a high-enough paying job? HA!
The only thing this DOES mean though, is that those who "don't do" can't really make the money on software. Unless they bring value to developers by helping the devs get work, work together, etc. If all you have is 10 lines of golden code and that is something someone else wrote and u can't do shit with it, then you have nothing because everyone has those 10 golden lines. Yet if you have the person who wrote them you have a competitive advantage.
